Portland Town Council. Opalotype or opaltype is an early technique of photography. Opalotypes were printed on sheets of opaque, translucent white glass; early opalotypes were sometimes hand-tinted with colors to enhance their effect. The effect of opalotype has been compared "to watercolor or even pastel in its softer coloring and tender mood."[1] "Opalotype portraits...for beauty and delicacy of detail, are equal to ivory miniatures."[2] The basic opalotype technique, involving wet collodion and silver gelatin, was patented in 1857 by Glover and Bold of Liverpool. Opalotypes exploited two basic techniques, using either the transfer of a carbon print onto glass, or the exposure of light-sensitive emulsion on the glass surface to the negative. Opalotype photography, never common, was practiced in various forms until it waned and disappeared in the 1930s. "Milk glass positive" is another alternative term for an opalotype. Opalotype is one of a number of early photographic techniques now generally consigned to historical status, including ambrotype, autochrome, cyanotype, daguerrotype, ivorytype, kallitype, orotone, and tintype. This and many other historical photographic methods are now considered alternative photographic techniques and are practised by a small number of dedicated artists.Monochrome portrait photograph of a man in a three piece suit.

Possibly Portland Town Council. Thomas Must, a wealthy Sydney merchant arrived in Portland in 1845. In 1855 prospect was built for Must to a design by local architect George Mathewson. The two storey home was built in expansive grounds with sweeping views of Portland Bay and the township. The stuccoed house is of Regency/Italianate style with a single storey verandah and single storey kitchen wing. In 1878 the original posted verandah was replaced by new verandah and a conservatory to a design of architect Daniel Nicholson. Nicholson had also been responsible for the design of the Assembly Rooms at the London Inn. Thomas Must was active in the Portland Community. He was a Trustee of the Port Philip Savings Bank, a Justice of the Peace, Treasurer of St. Peters Church at Bridgewater and the first Chairman of the Portland Borough Council. Prospect was Thomas Must’s home until his death in 1905. The building has been considerably altered over the years and much of the original Italianate character has been lost. Subsequent owners include B. Cunningham, G.S. Beresford (who changed the property’s name to Waterford), and long-term Liberal Senator Sir Magnus Cormack. Cormack was President of the Senate from 1971 to 1974. In 1976 the Prospect became an aged accommodation centre.Wooden Frame - light brown. Gold inner frame. Fawn mount.
